Which of the following is a novel written by Jane Austen?

The choice of Mansfield Park as a novel written by Jane Austen is accurate because it is indeed one of her major works, published in 1814. Austen is a renowned British novelist known for her keen observations of social manners and relationships, particularly among the British gentry in the early 19th century. Mansfield Park explores themes of morality, social class, and the nature of happiness through the story of Fanny Price, who is brought up at her wealthy relatives' estate.

In contrast, the other options represent works by different authors. The Rime of the Ancient Mariner is a poem by Samuel Taylor Coleridge, known for its exploration of nature, guilt, and redemption. The Lay of the Last Minstrel is a narrative poem by Sir Walter Scott that showcases the romantic and historical elements of Scottish culture. Confessions of an English Opium-Eater is an autobiographical work by Thomas De Quincey that delves into the effects of opium on his life and psyche. Each of these works belongs to a different literary tradition and period, clearly distinguishing them from Austen's novels.
